Tanks Playground v2.7
Tanks Playground v2.7

My tribute to the Tank Fever series by Lain.

Target difficulty is Normal; Advanced and Expert are beatable.
Rescue (10min) can come at 3 different places around the map.

Survival with stages (a bit like Helm's Deep)
Now with 7 stages, timings are relative to each stage's start.

Versus / Taaaaank!:
By night, experimental, not thoroughly tested.

Be sure to read the release notes.

Have fun and if you like the map, consider joining the Steam group, Tanks Playground L4D2 (TankPlaygrnd) to connect with other players and submit bugs/ideas.

Thanks to Necrofries and Lain.

Five Miles
Five Miles

Battle across five miles of psycho controlled apocalyptic highways, with 17 new enemies, as well as some returning allies. You don't get a break from zombies that easily, though: The bandits have weaponized them and plan to board your train! With a dynamic difficulty and 2 endings, Five Miles is my most ambitious map to date.

Intended for play on Easy or Normal!


!NEW! Major performance & stability improvements thanks to model optimizations by R.T. Frisk!

- Possible Bug -
If you hit performance dips in Five Miles try MEDIUM Effects Detail.

Beldurra 2
Beldurra 2 5/5 maps

The infection has left more than a wake of dead in Beldurra. Something big is living there now, and it brings down the Survivors' chopper as they attempt to fly over. Survivors will make their way from the wilderness, through the city, and finally to an all-original boss battle finale.

Beldurra 2 emphasizes an already-present arcade element while encouraging teamwork to accomplish tasks (often with multiple solutions) to proceed. There are more common infected and fewer SI, among other changes.

Features original textures, sounds, music and gameplay mechanics (lockpicking, building stations, etc.)

Enabling the Instructor is recommended.

Tank Challenge v1.2
Tank Challenge v1.2

An offshoot of Tanks Playground, a little idea we had while playing Tanks Playground with friends.

Survive waves of tanks with increasing difficulty until rescue after wave 10 (or 30, new!).

At each wave, one additional tank will spawn.

Have fun!
